U.S. Patent 6,554,014
A screw-in, cartridge-style, proportional, pilot-operated, spring-centered, spool-type, hydraulic
In neutral position, the HPE16-S67K blocks port 3 while 2, 4 and 5 are connected to each other.
When the remote pilot signal at 1 exceeds the force of the bias spring, the spool shifts
proportionally to the applied pilot pressure to allow flow from 3 to 4 through a load such as a
hydraulic cylinder or motor, and from 2 to 5 and to tank. Port 5 is to be used as a tank port only
with maximum pressure of 69 bar (1000 psi). On remote pilot signal at 6, the valve’s spool shifts
proportionally to the applied pressure in the opposite direction, reversing the flow direction. The
valve’s spool is non-symmetrical, providing meter-in control.
• Hardened spool and cage for long life.
• Cost-effective cavity.
• Excellent metering characteristics.
• Good Linearity.
• All HyPerformance™ products are tested to the rigorous standards of the NFPA specification
T2.6.1 and are tested at a verification level of 90% and an assurance of 99%.
